Never really had any issues to speak of with this laptop until this morning when I left my R61i on unplugged from the A/C adapter and the battery went dead shutting the machine down. When I went to plug it in it wouldn't turn on or anything...no sign of life at all....I removed the battery etc..etc but what I ended up doing was leaving the battery and ac cable off then an hour later I plugged in the ac and the battery and all is well again. Why did it scare me like that? Is it a sign of things to come?
